PEN-BEAM STANDARD FOR RULlNG-MACHINES.

, SPECIFICATION forming part of Letters Patent No. 284,666, datedSeptember 11, 1883.

Application filed January 9, 1883. (N0 model.)

To all whom it may concern Be it known that I, EDWIN J. PIPER, a citizenof the United States, residing at Springfield, in the county of Hampdenand State of Massachusetts, have invented new and useful Improvements inPen-Beam Standards for Ruling-Machines, of which the following is aspecification. v

This invention relates to improvements in paper-ruling machines; and itconsists in an improved construction of the pen-beam standards therefor,the object being to provide standards for supporting the saidbeam,which, more freely than heretofore, permit of a gravity adjustment ofthe beam and pens to the face of the paper upon the apron, and whichembody improved means for securing and retaining said beam in properposition and for adjusting it in any required direction.

In the drawings forming part of this specification, Figure 1 is anelevation of said penbeam standard embodying my improvements. Fig. 2 isalso an elevation, but partly in see-. tion. Fig. 3 is a plan view ofthe standard, partly in section, and one end of the pen-beam, the latterand the standard being shown connected together as they are when in use.

In the drawings, A is the standard a indicates the ordinary adjustablestandard-base, by which said standard is secured to the frame of theruling-machine. An adjusting-screw, a, passes through the upper end ofthe standard and projects downward a certain distance within the latter,which is made hollow, as shown. Said screw ais provided with a groovearound it near its end, (similar to that in bolt m, Fig. 1.) Aswivel-bolt sleeve, e, of an inverted-T shape, is attached to the lowerend of a screw a, the vertical arm of sleeve 6 being perforated toreceive the lower end of said screw, and a pin 18 placed transverselythrough said arm and through said groove in said screw,

' whereby the latter and said sleeve are secured vided with a head, d,which is perforated in a line across the axial line of said bolt.

The aforesaid standard A is provided with oblong vertical openings 2 2in opposite sides thereof, as in Figs. 1 and 2. The said swivelbolt 1)bears upon it two curved-faced washers,

a 11., adapted to fit against the sides of standard A and over saidopenings zz therein, bolt b passing through the latter and sleeve 6. Anut, 0 is fitted to bolt b. A pen-beam bolt,

an, provided near one end with a circular groove, w, is screwed throughthe head (I of the swivel-bolt b, so that the latter and bolt m occupypositions at right angles to each other. Set-nuts o and a are placed,respectively, on bolts m and a.

The pen-beam B is provided at each end I thereof with abolt-arm, t,which projects from 6 5 the end of said beam, and is provided with asuitable socket to receive the grooved end of the bolt m. A pin, 71, ispassed through said arm t one side of its center, and through saidgroove win bolt m to one side of the center of the latter, whereby saidbolt, while being secured to said arm, is allowed to turn freely thereinas it is operated in the head (I of bolt 1).

The usual adjustingscrew, 0, is employed for sliding the base 0 upon itsbed and retain-' ing it in proper position.

The ordinary pen-beam handle, I), for lift ing the pens f from the paperby swinging the bar B on the ends of bolts m, is secured to said bar.Said handle is also provided with the So usual adjusting-screw forregulating the bearing of the points of the pens upon the paper. Thepens f are secured in the clamp 7c in the ordinary way. I

The operation of my improvements is as follows: The operation of bolt atthrough the head (I of bolt 1) provides for adjusting bar B in thedirection of its length, to bring the points of the pens f to a properposition on the paper. The swivel-bolt I), being free (when nut o isunscrewed) to turn in sleeve 0, permits bolt m to adjust itself relativeto arm ton bar B. The connection between sleeve 0 and the lower end ofscrew (0 is such that said sleeve is free to oscillate thereon to acertain degree, and the openings 2 z in the sides of the standard Apermit the bolt 7) to oscillate with said sleeve, and by-screw a boltsI) and m are raised and lowered and secured at any desired position, andby lowering sleeve 0 to such a point as the weight of the pen-bar B mayforce it, and by unscrewing nut 0 to free bolt 7), the

parts to which said bar are attached are given consisting of thestandard A, having perforat- 10 such a free movement as prevents themfrom ed sides, the sleeve e, screw a, and the bolts 12 interfering inthe least with the self-adjustand m, combined and operatingsubstantially ment of said bar and pens to the surface of the as setforth.

5 apron and paper after which by screwing up nuts 0 and 'v, thesupportingparts of the bar EDWIN PIPER B are rigidly secured to saidstandard. \Vitnesses:
